GILDEMEISTER ENERGY SOLUTIONS FOR TELECOMMUNICATIONS SYSTEMS
Exacting demands in the telecommunications industry in terms of stability and safety rule out many traditional
energy supply services from the outset. From an environmental and economical perspective, there is no future for a
diesel generator, as the operative expenditure is too high.
Anyone looking for the ultimate solution will find it in CellCube. Discover the path to minimal operational
expenditures. The intelligent energy storage device drastically reduces supply and site costs. Easy and seamless
installation of CellCube storage systems enables plug-in replacements of existing legacy site equipment.

How the redox-flow-battery works
The liquid energy carriers are stored in two tanks and
are pumped through electro-chemical cells. Depending
on the applied voltage, the energy carriers are either
electro-chemically charged or discharged. In this context,
the electrical charge regulators and inverters function
as the interface to the electrical source, or, respectively,
to the appliance.
The power and the capacity of the CellCube can
be configured based on the requirements of your
telecommunications system!
The electro-chemical process that charges or discharges the battery takes place in the power stacks.
CELLCUBE – THE INTELLIGENT ENERGY MANAGER
CellCube‘s principle is based on a redox-flow-battery, combines all telecommunications technology, including the
power supply, in a single unit which concentrates on efficient energy management: remote maintenance, DC / DC
converter for connection to the SunCarrier photovoltaic system or similar, connection of a diesel generator with a
clever control system, outputs for additional equipment such as monitoring cameras or lighting.
Potential applications
• As a replacement for high-maintenance and
environmentally damaging battery systems and
diesel generator sets
• In weak grid with an unstable network
• As an off-grid solution in areas without grid
connection
• Suitable for all signal transmission stations
• Scalable for multi-operator sites
Benefits of CellCube
• Reduction of the Total Cost of Ownership
• Eliminating or mitigating constant increases in
diesel prices
• Easy integration into DC telecommunication
infrastructure
• Elimination of service and maintenance cost of
legacy storage solution
• Environmentally friendly and reusable
• Simple integration into standard online and remote
maintenance systems

WORTHWHILE INVESTMENT Efficiency is best expressed in figures.Especially if compared to diesel generators and conventional batteries, it quickly becomes clear that a CellCube
pays off on a number of levels when it comes to the stable supply of telecommunications networks.
Total Cost of Ownership
Comparison: diesel generator and lead battery compared to SunCarrier 22 and CellCube FB 10-40 (period of 20 years).
A 10 kW diesel generator charges a lead battery and powers the base station. When the battery is full, the
generator stops and the lead battery powers the unit. Alternative: one CellCube FB 10-40 with SunCarrier 22
with 14 kWp.
You save 135,000 litres of diesel in 20 years
Assuming a diesel price of EUR 1.20/l and an inflation rate of 3 % per year, the break even is reached after
around 5 years. Additional 356 tons of CO2 will be saved over 20 years.
